Substitute Part Grouping Explanation

Substitute parts for the VS-MBR1635PBF are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalents maintain identical electrical specifications and package configuration. These parts are interchangeable without circuit modification:

Voltage - DC Reverse (Vr) (Max): 35 V
Current - Average Rectified (Io): 16 A
Voltage - Forward (Vf) (Max) @ If: 630 mV @ 16 A
Package / Case: TO-220-2
Mounting Type: Through Hole

Parametric Equivalents meet or exceed the electrical requirements of the original part while maintaining the same package and mounting configuration. These parts function identically in the circuit:

Voltage - DC Reverse (Vr) (Max): 35 V or higher
Current - Average Rectified (Io): 16 A or higher
Voltage - Forward (Vf) (Max) @ If: 630 mV or lower
Package / Case: TO-220-2
Mounting Type: Through Hole

Upgrade Parts provide enhanced performance characteristics, such as extended operating temperature range or higher voltage ratings, while maintaining mechanical compatibility and electrical sufficiency:

Voltage - DC Reverse (Vr) (Max): 35 V or higher
Current - Average Rectified (Io): 16 A or higher
Operating Temperature - Junction: Extended range
Package / Case: TO-220-2
Mounting Type: Through Hole

Cross-Manufacturer Alternatives are sourced from different manufacturers and may have slightly different electrical characteristics while remaining functionally suitable for the application.

Engineering Selection Recommendations

Direct Replacement (Preferred): VS-MBR1635-M3 and MBR1635-E3/45 are direct electrical and mechanical equivalents to the discontinued VS-MBR1635PBF. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, maintain identical electrical specifications, and are classified as Active products. These parts are suitable for direct substitution without circuit redesign. VS-MBR1635-M3 offers higher inventory availability (785 Pcs) and includes capacitance specification (1400 pF @ 5V, 1MHz).

Enhanced Performance Alternative: MBR1635G, manufactured by onsemi under the SWITCHMODE™ series, provides identical electrical performance with an extended maximum junction temperature rating of 175°C compared to 150°C for the original part. This part is Active and suitable for applications requiring higher thermal margin. The TO-220-2 package maintains mechanical compatibility.

Cross-Manufacturer Option: STPS1545D, manufactured by STMicroelectronics, offers higher voltage rating (45 V vs. 35 V) and extended junction temperature (175°C). However, this part has a lower average rectified current rating (15 A vs. 16 A) and higher forward voltage drop (840 mV @ 30 A). This part is suitable only when the application can tolerate the reduced current capacity and increased forward voltage characteristics.

All substitute parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited), matching the compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can VS-MBR1635-M3 be used as a direct replacement for VS-MBR1635PBF?

A: Yes. VS-MBR1635-M3 is a direct equivalent with identical electrical specifications (35 V, 16 A, 630 mV forward voltage) and the same TO-220-2 package. The primary difference is product status: VS-MBR1635-M3 is Active while VS-MBR1635PBF is discontinued. No circuit modification is required.

Q: What is the difference between MBR1635-E3/45 and VS-MBR1635-M3?

A: Both parts are direct electrical equivalents with identical voltage, current, and forward voltage specifications. The primary difference is packaging: MBR1635-E3/45 is supplied in Tube packaging, while VS-MBR1635-M3 is also supplied in Tube packaging. Both are Active products from Vishay. Selection between these parts depends on inventory availability and supplier preference.

Q: Is MBR1635G a suitable replacement?

A: Yes. MBR1635G maintains identical electrical specifications (35 V, 16 A, 630 mV forward voltage) and the same TO-220-2 package. The advantage is an extended maximum junction temperature of 175°C versus 150°C for the original part. This part is manufactured by onsemi and is Active. It is suitable for applications requiring higher thermal performance.

Q: Can STPS1545D replace VS-MBR1635PBF?

A: STPS1545D is not a direct replacement. While it maintains the same package (TO-220-2) and offers higher voltage rating (45 V), it has a lower average rectified current rating (15 A vs. 16 A) and higher forward voltage drop (840 mV @ 30 A vs. 630 mV @ 16 A). This part is suitable only when the application can tolerate reduced current capacity and increased power dissipation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the original VS-MBR1635PBF.

Q: What is the operating temperature range difference between MBR1635G and the original part?

A: MBR1635G has a maximum junction temperature of 175°C, compared to 150°C for VS-MBR1635PBF. Both parts maintain the same minimum junction temperature of -65°C. This 25°C difference provides additional thermal margin in high-temperature applications.

Q: Are there any package differences between the substitute parts?

A: All substitute parts use the TO-220-2 package with Through Hole mounting, maintaining mechanical compatibility with the original VS-MBR1635PBF. Packaging format (Tube vs. other formats) may vary by supplier but does not affect electrical or mechanical performance.
